Probably the mid speed needle. the one on the opposite side of the carb in comparison to the LSN.

Edit: this thread is still getting posts !

Not for a while, but still getting views. 21,907 and counting.

I said a while back that when I was done with the AB modified stage(2) O.S.21TM project I would give out the gearing I was using. I forgot until I just saw the pictures on my Photobucket when posting a few pics in another thread.

After trying the revo gearing and still having the power to pull even taller gearing, I had to go custom.

This gearing is wicked....if you don't know what you are doing, you can smoke your clutch, the gearing or even your engine. As you can see from the pics taken last year some time, both the Revo combo and the Jato combo mesh perfectly and have been tested numerous times by me.

Here are both combo's I came up with. Both Revo and Jato pitch .08 and 1. I will let you guys count the teeth yourself to come up with the nasty gear ratio I was running.

I'm back in this thread! Been away for while (not jail), but flying edf jets. anyways got my .21 jato going again and it ran just awesome. I need a refreshing answer in regards to traxxas clutch shoes for the o.s. .21 jato. Should I use the clutch shoes for the revo 3.3 or jato 3.3? Revo are bigger, but is there a differnce in spring tension also. I'm at don't have the time today to read through the thread and find the answer, but i'm running the cars after work today so I'm crunched for time. I know aftermarket types are better, but for the amount of time left in my season traxxas's will work just fine. Thanks guys.

reason I ask this about changing the 2nd gear is because I came across these pinnion gears for 2ndgear for the jato. I have tried every cb and SG combo. I like the 18/36 and 19/36 for high speed. I figure if I could just get more top end 2nd gear gearing with the 18/36 combo my high top end speed will be better. I only use my os jato for high speed running for the most part. 100-150+ yards at a time.
